CONSTRUCTION OF SHIPS.

SPECIFICATION forming part of Letters Patent No. 538,799, dated May 7, 1895. .Applicatien filed December 17,1894. Serial No. 532,034. (No model.)

To all whom t may concern: l

Be it known that I, SINCLAIR STUART, of Plainfield, in the county of Union and State of New Jersey, have invented a new and useful Improvement in the Construction of Ships or other Vessels, of which the following is a specification.

This improvement relates to ships and other vessels constructed entirely of steel or iron or to what are known-as composite vessels constructed partly of steelor iron and partly of wood. The construction which#` constitutes my said improvement is mainly distinguished from the construction heretofore common in that in the common construction the frames so called have the form of ribs running continuously outward from the'keel through the bottom and thence upward through the exterior structure of the vessel, but according to my improvement the main frames are arranged lengthwise of the vessel and run continuously or Without interruption throughout the whole or any portion of the length of the exterior structure thereof. By this arrangement of the frames 'and the combinations hereinafter described and claimed whereby the so arranged frames are braced, I am enabled to construct a vessel having greater longitudinal stiffness and strength with less weight of metal as compared with vessels heretofore constructed.

Figure l representsa transverse section of I parts of one side and the bottom of a vessel embodying my invention. Fig. 2 represents a portion of the side of the vessel with the plating removed. Fig. 3 represents a horizontal section in the line 3 3 of Fig. 2.

Similar letters of reference designate corresponding parts in all the figures.

A A designate the main frames which run lengthwise of the vessel through the whole or any portion of the length of the exterior structure thereof and which may be united withthe structure of the stem and stern in any suitable ,mannen These longitudinal Aframes are represented as having a transverse section of what is known as channel form, the web of the channel being arranged horizontally as shown in Fig. 1.

B B are upright braces interposed at suitable intervals between the longitudinal frames A A. These braces are represented as so arranged in alignment with each other (see Fig. 2) thatthey resemble ribs which are interrupted only Where the longitudinal frames A A intervene. The said bracesB B are represented as made of two kinds of channel steel or channel iron, those B being'of a width equal to that of the longitudinal channel frames A and those B. being much narrower.. The said braces have the webs of their channels arranged crosswise of. the vessel and their fisanges parallel withv the sides thereof as shown in Fig. 2 and all are so arranged that the plating C of the vessel may lie against the outer flanges. The wider braces B are represented as less numerous than the narrower ones B', the wider and narrower ones being placed at regular intervals. The braces B are united with the longitudinal frames A A bytransversely arranged angle clips a a which are riveted to the said braces and frames above and,below the latter; and

"ing of the vessel.

D are the deck beams of the vessel represented as of channel form, riveted through their anges directly to the webs of the said frames A by rivets c c as shown in Figs. 2 and 3 and also riveted through their own webs and to the webs of the Wide braces B by rivets dd.

E are the margin strakes of the decks secured to the inner anges of the longitudinal frames A by angle bars e which run parallel with the said frames and are riveted to the said frames and strakes.

F are bracket plates which are secured to the narrow braces B by being riveted by rivets g directly to thc webs of said braces. These bracket plates F are also fastened to the margin strakes E by angle bars h riveted to the said plates and strakes.

G are bracket plates arranged one below each deck beam D close to the webs of the wider braces B and riveted by rivets Z directly the narrower braces B have their inner ICO to the said Webs. These plates G are also fastened to the lower anges of the deck beams by angle bars i riveted to the said flanges.

II are bracket plates arranged one above each lower deck beam D and close to the webs of the wider braces B and riveted by rivetsj directly to said webs. These bracket plates II are also fastened to the margin strakes and to the deck beams by angle irons 7c which are riveted to the said plates and also riveted to the upper iianges of the deck beams through the margin strakes.

In carrying out this invention the bottom of the vessel may be constructed in any suitable manuel'. In the example represented the vessel has a water ballast bottom and is represented as constructed according to my United States Letters Patent No. 526,823, dated October 2, 1894, except that it has chan-v nel plates I running continuously through it above the transverse door channels J.

What I claim as my invention isl. In the exterior structure ofa ship orother vessel, the combination of main frames A of channel form arranged lengthwise of the vessel and running continuously throughoutany portion of the length thereof with their Webs located horizontally, narrower upright chan# nel braces B and wider upright channel braces B interposed between and abutting against said frames, transversely arranged angle clips a, riveted to said frames A and to said wider braces B, and angle bars b which are arranged lengthwise of the vessel between said wider braces B and each of which is riv eted to one of said frames A and to two or more of said narrower braces B', substantially as herein described.

2. In a ship or other vessel, the combination of main channel frames arranged lengthwise of the vessel and running continuously through any portion ot' its length at the sides thereof, interrupted upright braces interposed between said frames and abutting against said frames, and deck beams of channel form riveted through their own flanges to the webs of said channel frames and riveted through their own webs to the webs of said upright channel braces, substantially as herein set forth.

SINCLAIR STUART.
